Problems solved by technology

Cars use pneumatic or hydraulic brakes when going down long and steep slopes. Although good braking effects can be achieved, for heavy vehicles with a large load of more than nine meters, the effect of using pneumatic or hydraulic brakes is limited after all, and Frequent braking of the brake assembly under heavy load conditions is prone to lock-up failure

Abstract

The invention relates to a lorry hydrodynamic retarder impeller machining method. The machining method comprises the steps of wax mold manufacturing, wax mold finishing, wax mold tree assembly, module cleaning, wax mold shell manufacturing, dewaxing, wax dewatering, wax recovery and molded shell roasting. The machining method has the following advantages: the machining method is realized through the steps of wax mold manufacturing, wax mold finishing, wax mold tree assembly, module cleaning, wax mold shell manufacturing, dewaxing, wax dewatering, wax recovery and molded shell roasting, can synchronously machine multiple wax molds through wax mold tree assembly to realize batch production, and can recycle wax through wax dewatering and wax recovery to reduce the production cost.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a processing method for an impeller of a hydraulic retarder of a truck. Background technique [0002] The hydraulic retarder is also called the hydraulic retarding device. Cars use pneumatic or hydraulic brakes when going down long and steep slopes. Although good braking effects can be achieved, for heavy vehicles with a large load of more than nine meters, the effect of using pneumatic or hydraulic brakes is limited after all, and Frequent braking of the brake assembly under heavy load conditions is prone to lock-up failure. Therefore, the state stipulates that passenger vehicles over nine meters and trucks over twelve meters must be equipped with retarder auxiliary braking devices. The stator of the hydraulic retarder is also the retarder housing, which is connected to the rear end of the transmission or the vehicle frame, and the rotor is connected to the transmission sh...
