Steering Angle Detecting Device for Pin Articulated Vehicles

Abstract

The invention discloses a pin shaft hinged vehicle steering angle detection device which comprises a front vehicle frame and a rear vehicle frame which are hinged together through a pin shaft; a pin shaft press plate is arranged on one of the end surfaces of the parts, outside the pin holes of the rear vehicle frame, of the pin shaft in a pressing manner; the pin shaft hinged vehicle steering angle detection device further comprises a shit block, a shift rod and a shift rod shaft; a bracket is mounted on the pin shaft press plate; the shift block is fixed on the front vehicle frame; the shift rod shaft is mounted in the bearing support of the bracket through a bearing; one end of the shift rod is connected with the shift rod shaft; the other end of the shift rod is inserted in a notch in the lower end of the shift block; the shift rod and the shift rod shaft guarantee each other against relative rotation; the shift rod is connected with the inner wall of the notch in a clearance fit manner; the input shaft of a shaft angle encoder is fixed connected with the upper end of the shift rod shaft through a coupling; and the notch in the lower end of the shift block is connected with an arc-shaped beam in a clearance fit manner. The pin shaft hinged vehicle steering angle detection device can accurately detect the relative steering angle of the front and rear vehicle frames and eliminate steering angle error caused by relative twisting and pitching of the front and rear vehicle frames, and has excellent popularization and application values.

Description

technical field [0001] The invention relates to a vehicle steering angle detection device, in particular to a pin shaft hinged vehicle steering angle detection device. Background technique [0002] The function of the steering system is to control the driving direction of the vehicle. The system should be able to keep the vehicle running in a straight line stably and flexibly change the driving direction according to the requirements. The basic requirements for the steering system are light and flexible operation, stable and reliable operation, and economical and durable use. The steering performance is an important factor to ensure the safe driving of the vehicle, reduce the labor intensity of the driver, and improve the work productivity. The steering system is a key assembly that determines the safety and operating efficiency of engineering vehicles. Engineering vehicles such as loaders, road rollers, etc. often use pin hinges to achieve good turning performance. The fra...
