Embodiment 1

[0029] Such as Figure 1-2 An off-road vehicle with a rear engine is shown. The off-road vehicle is an off-road touring vehicle or an off-road passenger vehicle, which includes a chassis 1, an engine 2, a transmission 3, a transfer case 4, a front axle 5 and a rear axle 6. The bottom end of the engine 2 is installed at the rear of the chassis 1, the front end of the engine 2 is provided with a gearbox 3, the engine 2 is in transmission connection with the gearbox 3, and the front end of the gearbox 3 is connected to the transfer via a first drive shaft 7. The input end of the transfer case 4 is connected, the first output end of the transfer case 4 is connected to the front axle 5 through the second transmission shaft 8, and the second output end of the transfer case 4 is connected to the rear axle through the third transmission shaft 9 6Connect.

[0030] The gearbox can produce different gear ratios between the engine and the wheels during the driving of the car. Gear shifting ...

Embodiment 2

[0039] In this embodiment, except that the technical solution is different from embodiment 1, other technical features are the same as that of embodiment 1:

[0040] Such as image 3 As shown, the off-road vehicle includes a front axle 5 and two rear axles 6. A front tire is installed at both ends of the front axle 5; a rear tire is installed at both ends of each rear axle 6 ; Between the two rear axles 6 through the fourth transmission shaft 17 transmission connection. Through the above technical solution, the engine is placed at the rear, and the six tires are driven by the transfer case 4. The transfer case 4 transmits power to the rear axle 6 close to the transfer case 4 through the third transmission shaft 9 and is close to the transfer case 4. The rear axle 6 of the power case 4 transmits power to the other rear axle 6 through the fourth transmission shaft 17, thereby realizing the driving of the rear tires.

Embodiment 3

[0042] In this embodiment, except that the technical solution is different from embodiment 1, other technical features are the same as that of embodiment 1:

[0043] The off-road vehicle includes two front axles 5 and two rear axles 6, each of which is equipped with a front tire at both ends; each of the rear axles 6 is equipped with a rear tire at both ends. The two front axles 5 are connected by a fifth drive shaft; the two rear axles 6 are connected by a sixth drive shaft.

[0044] Through the above technical solution, the engine is placed at the rear, and the eight tires are driven by the transfer case 4. The transfer case 4 transmits power to the front axle 5 close to the transfer case 4 through the second transmission shaft, and is close to the transfer case 4. The front axle 5 of the transmission case 4 transmits power to the other front axle 5 through the fifth transmission shaft transmission, thereby realizing the driving of the front tires; the transmission case 4 transmi...

Abstract

The embodiment of the invention discloses an off-road vehicle with a rear engine and a using method thereof, and relates to the technical field of vehicles; the off-road vehicle comprises a chassis, an engine, a gearbox, a transfer case, a front axle and a rear axle, wherein the bottom end of the engine is arranged at the rear part of the chassis, the front end of the engine is provided with the gearbox, the engine is in transmission connection with the gearbox, the front end of the gearbox is connected with the input end of the transfer case through a first transmission shaft, a first outputend of the transfer case is connected with the front axle through a second transmission shaft, and a second output end of the transfer case is connected with the rear axle through a third transmissionshaft. A power transmission system comprising the engine and the gearbox is arranged behind the tail of the off-road vehicle, thereby facilitating the reasonable arrangement of the chassis equipmentof the whole vehicle; the center of gravity of the vehicle mass is reasonable, and the braking forward inclination can be effectively reduced, so that the space at the bottom of a cab positioned at the front part of the vehicle is more spacious, and the riding comfort is improved; since the occupants are mainly concentrated in the front and middle of the vehicle, so the occupants are less affectedby engine noise.

Description

Technical field [0001] The embodiment of the present invention relates to the field of vehicle technology, in particular to an off-road vehicle with a rear engine and a method of use thereof. Background technique [0002] In modern vehicle design, the engine is the heart of the vehicle, but it is also the main source of noise. [0003] At present, off-road buses or off-road motorhomes modified from off-road truck chassis generally adopt the design concept that the engine is arranged at the front of the vehicle and the passenger area at the rear of the vehicle. However, such a design has certain defects: the vehicle is in the process of driving, The noise generated by the engine work will be transmitted from the front of the car body to the rear of the car, which will make people in the rear passenger area always suffer from noise, which will greatly affect the comfort of passengers in the car. In addition, in order to accommodate the engine underneath, the floor of the off-road tr...
