Abstract
The utility model relates to a front suspension device of a sleigh car, which comprises a master pin seat (4), an upper cross arm assembly (10), a lower cross arm assembly (11), a shock absorber (12), a steering rocker arm (2) and a master pin shaft (5), wherein the master pin shaft (5) passes through the master pin seat (4), and the master pin shaft (5) can rotate in the master pin seat (4); an outer spline on the master pin shaft (5) is matched with an inner spline on the steering rocker arm (2), and simultaneously, the steering rocker arm (2) is limited not to be pushed out from the master pin shaft (5) through a check ring (1) after being assembled to the master pin shaft (5), and thus, the shock absorption stroke is big, the running stability of the car is good, the riding comfort of staffs is improved, the overall maintainability is good, the use cost is low and the appearance has high rot resistance and is good.
Description
Technical field:
The utility model relates to the front suspension of a kind of snowfield with car, particularly relates to a kind of front suspension of sledge vehicle.
Background technology:
At present, ski bob adopts independent suspension more, its inner body all adopts non-removable connection mode, as captive joint modes such as riveted joint, welding, its shortcoming: one, the front suspension maintainability is poor, and two, need integral replacing, working service cost height behind the part failure, three, be difficult for doing anti-rust treatment, appearance poor after the front suspension welding.
Summary of the invention:
In order to improve the performance of existing ski bob front suspension, improve vehicle run stability and personnel's travelling comfort, improve existing front suspension shortcoming, the object of the present invention is to provide a kind of front suspension structure that can on snowmobile, use.
The purpose of this utility model can reach by the following technical programs, a kind of front suspension apparatus of ski bob, comprise the combination of alternation of hosts's key seat, Top Crossbeam, lower cross arm combination, damping its, be provided with pitman arm above the stub seat, thereunder be provided with the stub axle, the stub axle passes the stub seat, the stub axle can be rotated in the stub seat, male splines on the stub axle cooperates with female splines on the pitman arm, and driving torque is after pitman arm is assembled on the stub axle simultaneously; The top of described pitman arm is provided with back-up ring and releases from the stub axle by back-up ring restriction pitman arm, and bolts assemblies is on pitman arm, and fixedly pitman arm prevents that pitman arm from rotating.
Bumper, Top Crossbeam combination, lower cross arm combination are connected with the stub seat by bolt respectively, form revolute pair.
Whole front suspension is connected with car body by bolt.
Beneficial effect:
The beneficial effects of the utility model are: the damping stroke is big, and vehicle run stability is good; Improved the traveling comfort that personnel take; Whole maintainability is good, and use cost is low, and the outward appearance anti-corrosive properties is strong, good appearance.
Description of drawings
