Abstract
The utility model relates to a novel reducer hydraulic pressure bushing device which comprises a main elastic spring, a core, frameworks and an outer pipe, wherein the main elastic spring, the core and the frameworks are integrated, the frameworks are positioned around the main elastic spring, and the core is positioned in the center of the main elastic spring; the outer pipe is assembled on the outer edge of the main elastic spring to form a left chamber and a right chamber, and the left chamber and the right chamber are communicated by a flow channel. The novel reducer hydraulic pressure bushing device can obtain high damping and high rigidity and eliminate the road excitation under low frequency and large amplitude so as to improve the chassis vibration isolating effect.
Description
Technical field
The utility model relates to chassis system vibration damping field, particularly relates to a kind of new type speed reducer hydraulic bushing device.
Background technique
The chassis shock mitigation system is the part of vehicle complete vehicle vibration, and it all has bigger influence to body vibrations and car room noise level.The quality of chassis shock mitigation system directly influences people's riding comfort.Automobile travels on various road surfaces, because the caused vibrational excitation of Uneven road, the chassis plays crucial effects.
From present developing of automobile industry, because the price that bush type suspends is low, the rigidity adjustability is good, manufacturing process is simple, advantages such as it is little to take up room, it is gained great popularity in automobile chassis shock mitigation system field, but simple pure glue lining is to satisfy the requirement that high rigidity, high damping are provided at low frequency, large amplitude, thereby presses for a kind of hydraulic bushing to satisfy the vibration isolating effect of chassis shock mitigation system.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of new type speed reducer hydraulic bushing device, can not provide the requirement of high rigidity, high damping to solve pure glue lining under low frequency, large amplitude operating mode.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of new type speed reducer hydraulic bushing device is provided, comprise elasticity master spring, fuse, skeleton and outer tube, described elasticity master's spring, fuse and skeleton sulfuration are one, wherein, described skeleton be positioned at elasticity master spring around, described fuse is positioned at the middle part of elasticity master spring; Described outer tube is assemblied in the outer rim of described elasticity master's spring, forms left chamber and right chamber; Described left chamber and right chamber are communicated with by runner.
Interference fit between the outer tube of described new type speed reducer hydraulic bushing device and the elasticity master spring.
The fuse of described new type speed reducer hydraulic bushing device is welded by two panel beating materials, and is waist-shaped hole.
Elasticity master's spring of described new type speed reducer hydraulic bushing device has four collision blocks, and at side direction collision block withdrawing pattern.
The left chamber and the right chamber of described new type speed reducer hydraulic bushing device are wedge shape and full of liquid, and the top is equipped with sealed muscle.
Beneficial effect
Owing to adopted above-mentioned technological scheme, the utility model compared with prior art, have following advantage and good effect: the utility model is because the side direction collision block withdrawing pattern of elasticity master spring, by touch the face contact by line, replaced common face directly to contact, improved the vibration isolating effect under the automobile high pulling torque operating mode with face.The utility model is not only spacing rationally, can under limited conditions, play good displacement control action to power assembly, and reasonable in design, effective vibration and noise reducing under various operating modes, especially at idling operation and generally quicken, the cruising condition effect of vibration and noise reduction is good.
Description of drawings
Fig. 1 is a main sectional view of the present utility model;
Fig. 2 is a plan view of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Mode of execution of the present utility model relates to a kind of new type speed reducer hydraulic bushing device, as depicted in figs. 1 and 2, by elasticity master spring 4, fuse 1, skeleton 2, outer tube 3 is formed.2 sulfurations of described elasticity master's spring 4 and fuse 1, skeleton are one, wherein, described skeleton 2 be positioned at elasticity master spring 4 around, described fuse 1 is positioned at the middle part of elasticity master spring 4.Described elasticity master's spring 4 has four collision blocks, side direction collision block withdrawing pattern.Described fuse 1 by being welded, is waist-shaped hole by two panel beating materials.Described outer tube 3 and elasticity master spring 4 are by can under the liquid, interference is assembled into one, and formation left chamber 5 and right chamber 6, left chamber 5 and right chamber 6 are wedge shape and full of liquid, the top is equipped with sealed muscle, described left chamber 5 and right chamber 6 are communicated with by runner, thereby form the double flow channel system, reach the purpose that improves damping.The utility model has realized providing under low frequency, the large amplitude operating mode purpose of high rigidity, high damping, satisfies the requirement of car load NVH characteristic.
Be not difficult to find that the utility model improves the vibration isolating effect under the automobile high pulling torque operating mode because the side direction collision block withdrawing pattern of elasticity master spring by touched the face contact by line, has replaced common face directly to contact with face.The utility model is not only spacing rationally, can under limited conditions, play good displacement control action to power assembly, and reasonable in design, effective vibration and noise reducing under various operating modes, especially at idling operation and generally quicken, the cruising condition effect of vibration and noise reduction is good.
