The invention discloses a vehicle attitude adjusting valve group, and belongs to the application field of hydraulic machinery and motor vehicles. The valve group comprises an A-way oil return valve, a B-way oil return valve, an oil discharge flow regulating valve, a hydraulic lock, an oil charge flow regulating valve and an oil charge valve; the A-way oil discharge flow regulating valve and the A-way oil charge flow regulating valve are reversely connected in parallel, and the B-way oil discharge flow regulating valve and the B-way oil charge flow regulating valve are reversely connected in parallel to form a two-way flow regulating valve group separately; the A-way hydraulic lock, the two-way flow regulating valve group and the A-way oil charge valve are sequentially connected in series to form an A-way oil inlet path, and the A-way hydraulic lock, the two-way flow regulating valve group and the A-path oil return valve are connected in series to form an A-way oil return path; and the B-way hydraulic lock, the two-way flow regulating valve group and the B-path oil charge valve are connected in series to form a B-way oil inlet path, and the B-way hydraulic lock, the two-way flow regulating valve group and the B-way oil return valve are sequentially connected in series to form a B-way oil return path. According to the vehicle attitude adjusting valve group, the vehicle attitude lifting speed can be automatically adjusted, reasonable flow redistribution is achieved, and the vehicle attitude lifting stability is improved.
