The invention provides a bidirectional high-damping hydraulic auxiliary frame bushing, and belongs to the technical field of hydraulic bushings. The bidirectional high-damping hydraulic auxiliary frame bushing comprises an outer sleeve, an upper elastic main body and a lower elastic main body, wherein hydraulic oil is contained in the outer sleeve, the upper elastic main body and the lower elasticmain body are arranged inside the outer sleeve from top to bottom, a first hydraulic chamber is formed between the upper elastic main body and the lower elastic main body, a first concave part and asecond concave part are formed in the opposite sides of the lower elastic body and form a second hydraulic chamber and a third hydraulic chamber with the inner wall of the outer sleeve correspondingly, a first flowing channel used for communicating the first hydraulic chamber with the second hydraulic chamber is formed in the upper portion of the lower elastic body, and a second flowing channel for communicating the second hydraulic chamber and the third hydraulic chamber is formed in the lower portion of the lower elastic main body. The invention further provides an automobile using the bidirectional high-damping hydraulic auxiliary frame bushing. According to the bidirectional high-damping hydraulic auxiliary frame bushing and the automobile, the bidirectional high-damping hydraulic auxiliary frame bushing can meet the variable vibration condition of the automobile and is better in damping effect.
