Problems solved by technology

However, the original braking method of the 91 chassis is the gear brake. The gear brake has a great disadvantage, that is, the gear is easy to wear, which greatly reduces the service life of the gear, and is easy to damage the gearbox. Moreover, the safety and stability of the gear brake is poor, especially in the In mountainous areas with complex road conditions and steep slopes, this braking method can no longer meet the actual needs

Abstract

The invention discloses an agricultural vehicle four-wheel brake device which comprises a frame, front wheels, back wheels and a brake system. The brake system comprises a brake master pump, a brake foot bar, brake drums and a pipeline system, the brake master pump and the brake foot bar are installed on the frame, and the brake foot bar is connected with the brake master pump through a brake push rod. The brake drums are fixedly installed on the two front wheels and the two back wheels respectively, and the four brake drums are respectively connected with the brake master pump through the pipeline system. Brake pads and brake auxiliary pumps are installed in the brake drums, the brake pads are connected with the brake auxiliary pumps through sliding blocks, and the brake auxiliary pumps are connected with the brake master pump through the pipeline system. The agricultural vehicle four-wheel brake device is improved by an original gear brake mode of a 91 chassis, a four-wheel drum brake is achieved, braking is safe and stable, and the agricultural vehicle four-wheel brake device is better suitable for rural areas complex in road condition. The agricultural vehicle four-wheel brake device is simple in structure, soft in braking, safe and reliable.

Description

technical field [0001] The invention relates to a brake device, in particular to an oil brake device for agricultural vehicles. Background technique [0002] Agricultural vehicles play an important role in the daily life and production in rural areas of our country. They can be used for farmland operations during busy farming seasons and for short-distance transportation in normal times. They are one of the main means of transportation in rural areas. At present, the 91 chassis is commonly used on small agricultural vehicles in the market. After years of development and development, the technology of the 91 chassis is relatively mature, with strong stability and good operability. However, the original braking method of the 91 chassis is the gear brake. The gear brake has a great disadvantage, that is, the gear is easy to wear, which greatly reduces the service life of the gear, and is easy to damage the gearbox. Moreover, the safety and stability of the gear brake is poor, e...
