CN2382621Y - Shock absorber front axle of four wheel tractor - Google Patents

Abstract

The utility model discloses a shock absorption front axle of a four-wheel tractor, which comprises a front shaft and a vehicle frame. Two elastic suspension devices are respectively arranged on the left end and the right of the front shaft and between the laft side and the right side of the vehicle frame; the utility model comprises an elastic main plate, an elastic auxiliary plate, a center bolt, a spring clamp, a saddle clamp and a shaft tile. The utility model has novel structure and can cause shock absorption performance of the front wheels of the four-wheel tractor to be improved, and degree of wear can be reduced to cause the service life of the four-wheel tractor to be prolonged.

Description

A kind of four-wheeled tractor damping propons

The utility model relates to a kind of power actuated vehicle propons, especially a kind of four-wheeled tractor propons.

Existing four-wheeled tractor propons does not have any shock absorption device, and in the vehicle ' process, the suffered vibrations of chaufeur are bigger, and performance is particularly outstanding on rugged road.If the vehicle that long-duration driving is such, on the one hand will cause very big infringement to chaufeur healthy, also can cause the wearing and tearing of very big damage, particularly front-wheel to increase greatly to each parts on the vehicle on the other hand, thereby shorten the service life of four-wheeled tractor.Under the four-wheel condition of loading, it is liftoff front-wheel often to occur, and the uncontrollable travel direction of chaufeur, driver and vehicle safety can not get ensureing.

The purpose of this utility model is to overcome above the deficiencies in the prior art, and a kind of four-wheeled tractor propons that has shock absorption device is provided.

The technical solution of the utility model is: a kind of four-wheeled tractor damping propons, comprise front axle and vehicle frame, and between the left and right two ends of front axle and vehicle frame the right and left, a spring suspension device is housed respectively.

Above-mentioned spring suspension device comprises elasticity mainboard, elasticity subplate, center bolt, Spring Card, ride double-screw bolt and bearing shell, one termination roll coil of strip ear of elasticity mainboard, another termination is roll coil of strip ear not, one end of elasticity mainboard roll coil of strip ear and the preceding axis fixing plate of vehicle frame front end link, and the elastic plate support of an end of roll coil of strip ear and vehicle frame rear end does not link, and ride double-screw bolt and bearing shell combine as a whole front axle and vehicle frame.

Owing between the front wheel spindle of four-wheeled tractor and vehicle frame, shock absorption device is housed, on the one hand the damping performance of four-wheeled tractor front-wheel is improved greatly, abrasion loss reduces greatly, four-wheeled tractor single-piece damping performance is improved greatly, the wearing and tearing of each parts of vehicle body reduce greatly, thereby can prolong the service life of four-wheeled tractor greatly.Under the four-wheel condition of loading, headstock upwarps, this moment front-wheel can be under the shock absorption device effect along with the wheel shaft kiss the earth that falls automatically, chaufeur can be controlled travel direction fully, guarantees safety of person vehicle.Be contained in two spring suspension devices on vehicle frame both sides, be not parallel to each other, be splayed, can operate front-wheel steering easily like this, can reduce the pulling force of spring suspension device simultaneously, thereby prolong the service life of spring suspension device.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the utility model structure birds-eye view;

Fig. 3 is the utility model mounting structure scheme drawing.

Structure of the present utility model such as Fig. 1, Fig. 2, shown in Figure 3, comprise front axle 7 and vehicle frame 1, between front axle two ends, 7 left and right sides and vehicle frame 1 the right and left, a spring suspension device 16 is housed respectively, this device comprises elasticity mainboard 8, elasticity subplate 9, center bolt 11, Spring Card 4, ride double-screw bolt 5 and bearing shell 6, one termination roll coil of strip ear 2 of elasticity mainboard 8, another termination is roll coil of strip ear not, and the termination of elasticity mainboard roll coil of strip ear and the preceding axis fixing plate 3 of vehicle frame 1 front end link, an elasticity mainboard not end of roll coil of strip ear and the elastic plate support 10 of vehicle frame 1 rear end links, and ride double-screw bolt 5 and watt axle 6 combine as a whole front axle 7 and vehicle frame 1.The springing 16 that is installed in the vehicle frame both sides as can be seen from Figure 2 is not parallel to each other, and is splayed.

Claims (1)

1, a kind of four-wheeled tractor damping propons, comprise front axle and vehicle frame, it is characterized in that, at left and right two ends of front axle and the left and right both sides of vehicle frame one spring suspension device is housed respectively, this spring suspension device comprises elasticity mainboard, elasticity subplate, center bolt, Spring Card, ride double-screw bolt and bearing shell, one end roll coil of strip ear of elasticity mainboard, the other end is roll coil of strip ear not, one end of elasticity mainboard roll coil of strip ear and the preceding axis fixing plate of vehicle frame front end link, the elastic plate support of an end of roll coil of strip ear and vehicle frame rear end does not link, and ride double-screw bolt and bearing shell combine as a whole front axle and vehicle frame.
