Abstract

Abstract A hydrostatic drive vehicle and a subassembly for such vehicle wherein the subassembly includes an engine and a pump mechanism arranged in a manner such that when the subassembly is assembled into the vehicle the axes of the engine and the pump mechanism are transverse of the longitudinal axis of the vehicle. Other parts such as an alternator, coolant pump, air cooling fan and fan shroud also may be included in the subassembly.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 160 words
A mounting arrangement for the engine and pump mechanism of a hydrostatic drive vehicle which has two frame side members and a frame cross member extending between the two frame side members near one end of the vehicle comprising a longitudinally extending first bracket located adjacent one frame side member and connected thereto by a vibration dampening connection, one end of the engine and one end of the pump mechanism rigidly connected to said first bracket, the engine and the pump mechanism being located transversely of the frame, a second transverse bracket rigidly connected to the engine and connected by at least one vibration dampening connection to the frame cross member, a third engine-pump bracket rigidly connected to the engine adjacent the other end thereof and rigidly connected to the pump mechanism, and a fourth pump-frame bracket rigidly connected adjacent the other end of the pump mechanism and connected to the other frame side member by a vibration dampening connection.
Claim 2
Dependent Claim 160 words
A mounting arrangement for the engine and pump mechanism of a hydrostatic drive vehicle which has two frame side members and a frame cross member extending between the two frame side members near one end of the vehicle comprising a longitudinally extending first bracket located adjacent one frame side member and connected thereto by a vibration dampening connection, one end of the engine and one end of the pump mechanism rigidly connected to said first bracket, the engine and the pump mechanism being located transversely of the frame, a second transverse bracket rigidly connected to the engine and connected by at least one vibration dampening connection to the frame cross member, a third engine-pump bracket rigidly connected to the engine adjacent the other end thereof and rigidly connected to the pump mechanism, and a fourth pump-frame bracket rigidly connected adjacent the other end of the pump mechanism and connected to the other frame side member by a vibration dampening connection.
Claim 3
Dependent Claim 16 words
A mounting arrangement as in claim 1 wherein said pump mechanism comprises two axially aligned pumps.
Claim 4
Dependent Claim 14 words
A mounting arrangement as in claim 1 wherein said engine includes a coolant pump.
Claim 5
Dependent Claim 17 words
A mounting arrangement as in claim 3 wherein a fan wheel is mounted on said coolant pump.
Claim 6
Dependent Claim 14 words
A mounting arrangement as in claim 4 wherein a shroud surrounds said fan wheel.
Claim 7
Dependent Claim 41 words
A mounting arrangement as in claim 5 wherein an air duct is connected to said shroud and arranged to direct air from said fan through an oil cooler and a radiator located in said vehicle above said engine and pump mechanism.
Claim 8
Dependent Claim 183 words
A subassembly for assembly into a vehicle having two frame side members and a frame cross member near one end of the side frame members, the subassembly comprising, a longitudinally extending first bracket arranged to be located in the vehicle adjacent one side frame member and to be connected to said side frame member by a vibration dampening connection near one extremity of the bracket, an engine arranged to be located transversely of the vehicle and having one end connected rigidly to said first bracket, a pump mechanism arranged to be located transversely of the vehicle and having one end connected rigidly to said first bracket, a second transverse bracket rigidly connected to said engine and arranged to be connected by at least one vibration dampening connection to the frame cross member, a third engine-pump bracket rigidly connected to said engine adjacent the other end thereof and rigidly connected to said pump mechanism, a fourth pump-frame bracket rigidly connected adjacent the other end of said pump mechanism and arranged to be connected to the other side frame member by a vibration dampening connection.
Claim 9
Dependent Claim 183 words
A subassembly for assembly into a vehicle having two frame side members and a frame cross member near one end of the side frame members, the subassembly comprising, a longitudinally extending first bracket arranged to be located in the vehicle adjacent one side frame member and to be connected to said side frame member by a vibration dampening connection near one extremity of the bracket, an engine arranged to be located transversely of the vehicle and having one end connected rigidly to said first bracket, a pump mechanism arranged to be located transversely of the vehicle and having one end connected rigidly to said first bracket, a second transverse bracket rigidly connected to said engine and arranged to be connected by at least one vibration dampening connection to the frame cross member, a third engine-pump bracket rigidly connected to said engine adjacent the other end thereof and rigidly connected to said pump mechanism, a fourth pump-frame bracket rigidly connected adjacent the other end of said pump mechanism and arranged to be connected to the other side frame member by a vibration dampening connection.
Claim 10
Dependent Claim 15 words
A subassembly as in claim 7 wherein said pump mechanism comprises two axially aligned pumps.
Claim 11
Dependent Claim 14 words
A subassembly as in claim 7 in which said engine includes a coolant pump.
Claim 12
Dependent Claim 16 words
A subassembly as in claim 9 wherein a fan wheel is mounted on said coolant pump.
Claim 13
Dependent Claim 13 words
A subassembly as in claim 10 wherein a shroud surrounds said fan wheel.
Claim 14
Dependent Claim 41 words
A subassembly as in claim 11 wherein means are provided for connecting to said shroud an air duct which is arranged to direct air from said fan to an oil cooler and a radiator located in the vehicle above the subassembly.
