An adjustable steering arm

Abstract

The invention relates to an adjustable steering arm. The adjustable steering arm comprises a first steering arm body, a second steering arm body, a locking device and a sliding block. The first steering arm body comprises a transverse plate, a first protrusion and a second protrusion. The first protrusion and the second protrusion are arranged at the two ends of the transverse plate correspondingly and located on the two sides of the two ends of the transverse plate correspondingly. The second steering arm body is fixedly connected to the side, close to the transverse plate, of the first protrusion. The second protrusion is provided with a main pin hole and an axle hole. The main pin hole penetrates in the length direction of the transverse plate. The axle hole penetrates in the width direction of the transverse plate. The second steering arm body is provided with a groove penetrating in the length direction of the transverse plate. The sliding block is arranged in the groove and can slide in the groove in the width direction of the transverse plate. The locking device can fix the sliding block in the groove. According to the steering arm provided by the technical scheme, the steering trapezium size is adjustable, the effect that the installation size of a trapezium arm is qualified can be ensured, and thus the steering circle center of a vehicle wheel during steering is consistent.

Description

technical field [0001] The invention relates to the technical field of a steering arm, in particular to an adjustable steering arm. Background technique [0002] At present, the steering system on trolleys generally needs to consider Ackermann geometry, so there are also various types of steering arms with steering trapezoids. Due to the limitation of steering trapezoidal geometric parameters, most steering arms cannot be integrally formed, and two parts need to be welded or connected by other means. [0003] This structure is relatively easy to cause dimensional deviation, so that the angle and length of the actual steering trapezoid do not match the designed size, and the tire cannot achieve pure rolling during steering. Contents of the invention [0004] The technical problem to be solved by the present invention is how to provide a steering arm with adjustable size of the steering trapezoid, so as to ensure that the installation size of the trapezoidal arm is qualifie...
