Vehicle steering assembly and all-terrain vehicle

Abstract

The invention discloses a vehicle steering assembly and an all-terrain vehicle. The vehicle steering assembly comprises a yoke plate used for being fixedly installed on a direction column and two hinge balls fixed to the yoke plate, wherein the two hinge balls are arranged on the two sides of the yoke plate respectively in the axial direction of the direction column, so that the horizontal distance between the two hinge balls is reduced, the effective output distance produced by a steering track rod is increased, radius of turning a corner is reduced, the steering performance and the maneuvering performance of the all-terrain vehicle are improved, and the all-terrain vehicle can be better suitable for walking on rough topography; meanwhile, restraint is produced between the two hinge balls, the uniformity of movement, along with the yoke plate, of the two hinge balls is improved, the precision of the relative position between the two hinge balls is ensured, the connection structure of the two hinge balls and the yoke plate is simplified, the requirements for machining precision of the connection structure are lowered, machining cost is saved, and the failure rate is decreased.

Description

technical field [0001] The invention relates to a vehicle accessory and its application on a beach car, in particular to a vehicle steering assembly and the beach car. Background technique [0002] The vehicle steering system is an important part of the vehicle, especially for vehicles with large tires such as ATVs. The tires can contact the road with a large area to generate greater friction. With the unique tread pattern, the tires are not easy to Idling and slipping, it can walk freely on terrains that are difficult for ordinary vehicles to walk on, such as beaches, river beds, forest roads, streams and even worse deserts. The main uses are racing cars, family recreational vehicles, etc., and the usage is increasing year by year. The ATV steering system is generally composed of a steering handle, a steering column, a connecting plate, two hinged ball joints and two steering rods. The steering handle is fixed on the upper end of the steering column, and the two hinged bal...

Problems solved by technology

The ATV steering system is generally composed of a steering handle, a steering column, a connecting plate, two hinged ball joints and two steering rods. The steering handle is fixed on the upper end of the steering column, and the two hinged ball joints are fixed on the lower end of the steering column through the connecting plate. , the two steering rods are hinged one by one to the hinged ball joints to transmit the driving force of the steering column to the two front wheel steering knuckles respectively. In the prior art, the two hinged ball joints of the ATV steering system are independently set and Arranged side by side along the ATV horizontally, each hinged ball head is respectively fixed on the connecting plate through the taper shaft and the taper hole on the connecting plate. It is necessary to strictly ensure the symmetry of the two hinged ball heads and the consistency of their distance from the axis of the steering column. The processing accuracy is high, the processing of the taper hole and the taper shaft is difficult and costly, and it is necessary to set up fastening connectors corresponding to each hinged ball head. The connection structure is complex and the failure rate is high. Two hinged ball heads are assembled on the connecting plate. There are differences in the matching clearances of the steering handlebars, so when the steering handle is turned, the movement of the hinged ball head with a slightly larger fitment gap lags behind the other hinged ball head, so the steering consistency of the wheels is poor, and the wheel suspension structure is easily damaged; The reaction force of the hinged ball joint produces an axial component along the corresponding taper axis, which not only easily damages the connection structure between the hinged ball joint and the connecting plate, destroys the symmetry of the two hinged ball joints, but also causes the connecting plate to be affected by unbalanced forces. , it is easy to cause deformation of the connecting plate after long-term use; at the same time, in order to meet the installation needs and avoid structural interference, the two hinged balls are offset to the side where the corresponding steering rod is located, so when the steering column is turned, the effective distance output by the steering rod The maximum value is small, the maximum value of the wheel steering angle is also small, the turning radius is large, the steering ability is not good, and the maneuverability is poor
