Abstract
An intermediate bearing assembly of a transmission shaft of a lorry comprises a support assembly and an inner circular metal sleeve, the support assembly consists of a U-shaped support and a cover plate, and a rubber block is arranged between the support assembly and the inner circular metal sleeve. The U-shaped rubber block is adhered outside the inner circular metal sleeve to form an intermediate bearing backing ring, a bearing is assembled in the inner circular metal sleeve, and dustproof seals are arranged on two sides of the bearing. Twelve grooves are annularly uniformly distributed on the inner sides of the two sides of the rubber block of the intermediate bearing backing ring and eleven grooves are annularly distributed on the outer sides of the same for further damping and effective radiating. A cylinder at the bottom of the rubber block is matched with a circular hole at the bottom of the U-shaped support, and play and rotation are effectively prevented. The dustproof seals are provided with lip springs so as to prevent overflow of lubricating grease in case of failure of the dustproof seals and bearing oil seals. The intermediate bearing assembly can meet the requirement for service life of the lorry, and harms resulting from impact and dynamic deformation of the transmission shaft are effectively reduced.
Description
Technical field
The present invention is autotruck transmission shaft center support assembly, particularly can reduce the blastic deformation of propeller-shaft and the transmission shaft center support assembly of torsional deflection by actv..
Background technology
The transmission shaft center support assembly that adopts at present is very low service life. owing to ageing of rubber, dwindle, make circular center support gasket ring generation radial rotating and end float misalignment.Affect the damping performance of transmission shaft.The phenomenon that the very fast generation of center support assembly was lost efficacy.Dust seal and bearing seal lost efficacy and make grease excessive in addition, caused bearing rust even dry combustion method to damage.Because rubber rigidity causes greatly the car load vibrations larger.
Summary of the invention
The object of the invention is to: for autotruck provides a kind of requirement of satisfying automotive service life, can reduce the impact of transmission shaft and the transmission shaft center support assembly of the harm that dynamic deformation causes by actv..
HD truck transmission shaft center support assembly of the present invention, it forms bracket assembly by U-shaped support and cover plate, also has the circular metal inner sleeve, be rubber block between bracket assembly and the circular metal inner sleeve, it is characterized in that: the outer bonding profile of circular metal inner sleeve is that U-shaped rubber block forms the center support gasket ring, be equipped with bearing in the circular metal inner sleeve, the bearing both sides are with dust seal.For further damping and actv. heat radiation, uniform 12 grooves of the interior annular of the rubber block two sides of center support gasket ring, 11 grooves of exterior annular distribution.One cylinder is arranged at the bottom of rubber block, cooperates with the circular hole of U-shaped frame bottom, has further effectively prevented play and rotation.Make grease excessive in order to prevent that dust seal and bearing seal lost efficacy, described dust seal is the dust seal with the lip spring.
Description of drawings
Accompanying drawing has represented a kind of HD truck transmission shaft of the present invention center support assembly structure scheme drawing, wherein Fig. 1 has represented this HD truck transmission shaft center support assembly structure profile front view, Fig. 2 has represented this HD truck transmission shaft center support assembly structure cut away left side view, Fig. 3 has represented this HD truck transmission shaft center support assembly structure center support gasket ring profile front view, and Fig. 4 has represented this HD truck transmission shaft center support assembly structure center support gasket ring cut away left side view.
The specific embodiment
This as shown in drawings HD truck transmission shaft center support assembly of the present invention, it forms center support gasket ring that bracket assembly, circular metal inner sleeve and U-shaped rubber block bonding form and bearing, dust seal etc. by U-shaped support and cover plate and forms.Uniform 12 grooves of the interior annular of rubber two sides, 11 grooves of exterior annular distribution (uniform by 12 grooves).The U-shaped structure of the rubber of this structure and support and bottom cylinder can prevent center support ring radial rotating.The support both sides are with rib, and support both sides rib and bottom rubber cylinder can prevent that the center support annulate shaft is to play.Prevented that reason owing to the rotation of center support gasket ring and play from causing the inefficacy of center support assembly.Can reduce the blastic deformation of propeller-shaft and the harm that torsional deflection causes by actv..Reduce the vibrations of car load.Significantly improving the service life of propeller-shaft and transmission device. the groove of rubber ring both sides can be regulated the compression stiffness of product all directions and rotational stiffness simultaneously again so that product has the performance that becomes rigidity.Can also play the effect that makes the rubber heat radiation.The different needs to product compression stiffness and torsional stiffness of the distortion of Vehicle Propeller Shaft Supporting Bracket assembly on specific direction have been regulated simultaneously; Dust seal increases the lip spring makes its dust-proof effect better.And can prevent that grease is excessive, increase the life-span of bearing.Compare with original product and to have reduced rubber hardness, satisfy automobile on specific direction two kinds of distortion to the different needs with torsional stiffness of compression stiffness; Damping effect and the service life of transmission shaft center support assembly have been increased.
Above structure has improved load-carrying capacity and the damping performance of transmission shaft center support assembly.Can satisfy automobile fully to the requirement in service life of this product.Can reduce the impact of transmission shaft and the harm that dynamic deformation causes by actv..Greatly reduce the vibrations of car load.
