Articulated vehicle steering angle detector

Abstract

The invention discloses an articulated vehicle steering angle detector, and aims to accurately measure the relative steering angle of a front frame and a rear frame of a pin roll articulated vehicle. The left end of a steel belt is fixedly connected to a left end steel belt fixing frame, the left end steel belt fixing frame is in articulated juncture with a steel belt articulating frame fixedly connected to a pin roll, the right end of the steel belt is fixedly connected with a right end steel belt fixing frame fixedly connected with a bracing wire tip of a bracing wire displacement sensor, the bracing wire displacement sensor is fixedly connected to a support fixedly connected with the rear frame, a protective cover is fixedly connected to the rear frame and covers the whole bracing wire displacement sensor, a part of the steel belt is wound on the pin roll, and the bracing wire of the bracing wire displacement sensor and the steel belt are in a plane vertical to the axis of the pin roll. By adopting the articulated vehicle steering angle detector, the steering angle of the front frame and the rear frame of the articulated vehicle can be accurately measured.

Description

technical field [0001] The invention relates to a steering angle detection device, in particular to a steering angle detection device for an articulated vehicle. 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 frame of ...

Problems solved by technology

The existing steering angle detection technical solution is to install a linear displacement sensor with a large axial dimension across the two ends of the steering cylinder, and indirectly measure the steering angle of the vehicle by measuring the expansion and contraction of the steering cylinder. However, the long steering cylinder The location is relatively close to the ground, and the sensor is vulnerable to the impact of spilled and jumping materials during the working process of the vehicle, which may damage the sensor

There is a spherical joint installed at the joint between the front frame and the rear frame of an articulated vehicle, and there is a complex relative rotation between the two. If the detection device is not designed properly, it will easily cause a large error in the measurement of the rotation angle. Therefore, how to accurately measure the front and rear The relative steering angle of the frame becomes a key issue in the research of steer-by-wire system
