Turning angle detection device of wheel type loading machine

Abstract

The invention discloses a turning angle detection device of a wheel type loading machine. The turning angle detection device of the wheel type loading machine comprises a front frame and a rear frame which are hinged together through pin shafts, wherein a pin shaft pressing plate is pressed on one end surface of a pin shaft on the outer side of a pin hole of the rear frame. The turning angle detection device of the wheel type loading machine further comprises a big synchronous belt wheel and a small synchronous belt wheel, wherein the big synchronous belt wheel is fixed on the outer side of the pin shaft pressing plate through a big synchronous belt wheel shaft in the center of the synchronous belt wheel; a bracket is mounted on the front frame; a small synchronous belt wheel shaft is sleeved with the small synchronous belt wheel, and is mounted in a bearing pedestal of the bracket through a bearing; the big synchronous belt wheel and the small synchronous belt wheel are connected through a synchronous belt therebetween; the upper end of the small synchronous belt wheel shaft is connected with an input shaft of a shaft angle encoder above the small synchronous belt wheel shaft through a shaft coupler; and the axial line of the shaft angle encoder is consistent with the axial line of the small synchronous belt wheel shaft. The turning angle detection device of the wheel type loading machine can accurately measure the relative turning angle of the front frame and the rear frame, can eliminate the turning angle error caused by relative torsion and pitching of the front frame and the rear frame, and has good popularization and application value.

Description

technical field [0001] The invention relates to a vehicle steering angle detection device, in particular to a wheel loader steering angle detection device. Background technique [0002] As a special construction machine for loading and unloading piles of bulk materials and for light excavation, loaders have been widely used in various aspects of the national economy such as construction sites, mines, ports, warehouses, stockyards, etc., and have become important equipment for modernization. The steering system is a key assembly that determines the safety and operating efficiency of engineering vehicles. In order to achieve good turning performance, wheel loaders often adopt the pin hinged form. The frame of the vehicle is composed of two sections of the front and rear frames. The front and rear frames are connected by pin hinges, and the front and rear frames are kept or Changing the relative angle makes the vehicle run on the ground with different curve radiuses.
