Abstract

The invention discloses a parallel R-type automobile shock absorber for recovering energy by turbines and a method. The shock absorber is characterized in that a parallel capillary resistance adjusting section and a double-turbine energy recovery section are connected on a pipeline between an oil conveying port of an upper oil bin and an oil conveying port of a lower oil bin in series; the double-turbine energy recovery section comprises a one-way valve V1, a one-way valve V2, a generator G1, a generator G2, a turbine T1 and a turbine T2; hydraulic oil flows through the resistance adjusting section, the one-way valve V1 and the turbine T1 in sequence from an oil port A of the upper oil bin to enter the lower oil bin; when the hydraulic oil flows through the turbine T1, the turbine T1 drives a rotor of the generator G1 to operate and generate electricity, and oscillation consumed energy recovering of a stretching stroke is realized; and accordingly, the shock absorber can also realize oscillation consumed energy recovering of a compression stroke. According to the shock absorber and the method, the problem that the oscillation consumed energy cannot be recovered is solved; and meanwhile, the operating temperature of the hydraulic oil can be reduced, and the service life of the shock absorber is prolonged.

Description

technical field [0001] The invention relates to the field of hydraulic automobile shock absorbers, in particular to a parallel R-type automobile shock absorber and method for recovering energy from a turbine. Background technique [0002] The vibration reduction methods of automobiles mainly include hydraulic type, pneumatic type and electromagnetic type. The hydraulic type is currently the most widely used vehicle vibration reduction method. The hydraulic oil in the hydraulic shock absorber needs to produce damping during the oscillation process, and the process of producing damping is a process that consumes energy. We call the energy consumed by the oscillation process the oscillation energy consumption. At present, the vibration energy consumption of the hydraulic shock absorber is wasted energy because there is no vibration energy recovery device in the hydraulic shock absorber. [0003] Such as figure 1 As shown, this is an automotive shock absorber with parallel c...
