Problems solved by technology

Its disadvantages are: 1. Both the front and rear axles use hydraulic suspension devices, although the ride comfort is high, but the transportation capacity is reduced; 2. The shock absorption structure is complicated and there are many components, which reduces the reliability
Its weak point is: vehicle body is rigidly connected with engine, transmission box, and the vibration of engine is easily transmitted to driver's cab, causes poor ride comfort

Embodiment 1

[0027] Such as figure 1 As shown, the present invention comprises a vehicle body 1 and an engine 2 installed on the front portion of the vehicle body 1, and a belt 3, a clutch 6, a front gearbox 7, a transfer case 8, a front transmission shaft 9, a rear gearbox 10, and a power transmission sequentially. Rear drive shaft 11, rear axle assembly 12, also comprise the rear tire 13 that is installed in vehicle body 1 rear portion and rear axle assembly 12 is connected, front gearbox 7 is provided with drive shaft 18, and front gearbox 7 passes drive shaft 18 Installed on the elastic suspension front axle 4, the elastic suspension front axle 4 is connected with the vehicle body 1 and the transfer case 8 respectively, and the drive shaft 18 is connected with the front tire 5.

[0028] In this embodiment, after loading heavy goods, the vehicle body 1 is pressed down, and the transfer case 8, the front gearbox 7, the engine 2, etc. are driven down together by the elastic suspension fro...

Embodiment 2

[0030] Such as figure 2 , image 3 As shown, the difference from Embodiment 1 is that the elastic suspension front axle 4 includes a left upper plate 14, a right upper plate 15, a vertical plate 16, and an elastic steel plate 17, and the two ends of the left upper plate 14 and the right upper plate 15 are connected into a rectangle by a horizontal plate frame, the front end and the rear end of the rectangular frame are connected with the elastic steel plate 17 by the riser 16, the middle part of the elastic steel plate 17 is connected with the drive shaft 18, and the rear end of the rectangular frame is connected with the vehicle body 1.

[0031] In this embodiment, after the heavy cargo is loaded, the body 1 is pressed down, and the elastic steel plate 17 is compressed by the rectangular frame, which drives the transfer case 8, the front gearbox 7, the engine 2, etc. to be pressed down together, thereby reducing the size of the body 1 and the front gearbox. The included ang...

Embodiment 3

[0033] Such as Figure 4 As shown, the difference from Embodiment 2 is that the rear end of the rectangular frame is connected with the support 20 through the spring 19 , the rear end of the rectangular frame is connected with the vehicle body 1 , and the spring support 20 is connected with the transfer case 8 .

[0034]In this embodiment, after loading heavy goods, the vehicle body 1 is pressed down, and the spring 19 is compressed by the rectangular frame, and the spring 19 squeezes the support 20, driving the transfer case 8, the front gearbox 7, the engine 2, etc. to be pressed down together, so that The body 1 and the front gearbox 7 keep parallel or the angle remains constant, so that the torque of the engine 2 can be fully exerted; when the speed of the vehicle is fast and the vibration of the engine 2 is huge, the compression of the spring 19 can reduce the shock and increase the ride comfort When encountering potholes on the road surface, the front tire 5 enters a pit...

Abstract

The invention discloses a four-wheel drive tractor with an elastic suspension front axle and aims to provide an agricultural four-wheel drive vehicle with high transportation capacity, high taking comfort and high off-road capacity. The four-wheel drive tractor comprises a body, an engine which is arranged at the front part of the body, and a belt, a clutch, a front gearbox, a transfer case, a front transmission shaft, a rear gearbox, a rear transmission shaft, a rear axle assembly and rear tires which sequentially transfer power, wherein a driving shaft is arranged on the front gearbox; the front gearbox is arranged on the elastic suspension front axle through the driving shaft; both ends of a left upper plate and a right upper plate of the elastic suspension front axle are connected through transverse plates to form a rectangular frame; the front end of the rectangular frame is connected with a vertical plate, and the rear end of the rectangular frame is connected with a supporting seat through a spring; the vertical plate is connected with the supporting seat through an elastic steel plate; the middle of the elastic steel plate is connected with the driving shaft; the rear end of the rectangular frame is connected with the body; the supporting seat is connected with the transfer case. The technology is applicable to the four-wheel drive tractor and can also be applied to a two-wheel (single-wheel) drive tractor.

Description

technical field [0001] The invention relates to the field of agricultural vehicles, in particular to a four-wheel drive tractor with an elastic suspension front axle. Background technique [0002] Tractor is the main agricultural power machine, which can pull different agricultural implements for plowing, sowing, harvesting, transporting crops, etc. Tractors can be roughly divided into crawler tractors and wheeled tractors according to the way they move. Generally speaking, small tractors are mostly wheeled tractors, and large tractors are mostly crawler tractors. [0003] Wheeled tractors are the most commonly used tractors in rural areas in my country. The tractors at the rear of this tractor are mainly driven by the front two wheels (or single wheel), and the driving torque is often not fully utilized, resulting in the inability of the internal combustion engine to be fully utilized, which is easy to There is a situation of "can't exert strength". However, rural roads a...
