The invention relates to a frame type front auxiliary frame structure which comprises two longitudinal beams which are oppositely arranged in parallel, a front beam is arranged at the front ends of the longitudinal beams, a rear beam is arranged at the rear ends of the longitudinal beams, a bent pipe is connected to the rear ends of the longitudinal beams, a rear swing arm support is arranged on the inner bent side of the bent pipe, one end of an angle support is connected to the front beam, and the other end of the angle support is connected to the rear swing arm support. The other end of the angle support is connected to the longitudinal beam, the rear beam is connected with one side of a steering gear support, the other side of the steering gear support is connected to the longitudinal beam, and the longitudinal beam is further provided with a front swing arm support. The auxiliary frame is formed by installing and welding the tubular beam, the sectional material and the simple small stamping part, has the advantages of being few in stamping part, low in die cost and short in welding seam, and is equivalent to a full-stamping part installing and welding type auxiliary frame in performance.
本发明涉及一种框架式前副车架结构,包括两个相对平行设置的纵梁,所述纵梁的前端设置有前梁,后端设置有后梁,所述纵梁的后端连接有弯管,所述弯管的内弯侧设置有后摆臂支架,所述前梁上连接有角支架的一端,所述角支架的另一端连接在纵梁上,所述后梁上连接有转向器支架的一侧,所述转向器支架的另一侧连接在纵梁上,所述纵梁上还设置有前摆臂支架。通过管梁+型材+简易小型冲压件组焊而成的副车架,此种副车架具有冲压零件少,模具成本低,焊缝短的优点,而且性能上与全冲压件组焊式副车架相当。
