Abstract
The utility model belongs to the technical field of automobile parts and relates to a car auxiliary engine assembly which comprises end covers, a sealing ring, a C-shaped ring, an upper cover, a spring, an auxiliary engine shell body and a main shaft pin. The main shaft pin is installed in the auxiliary engine shell body through a bearing, the spring is arranged at the bottom of the main shaft pin through a gasket, a clamping groove is arranged on the inner wall of the auxiliary engine shell body below the spring, the C-shaped ring is installed on the clamping groove, and the upper cover is arranged between the spring and the C-shaped ring. The car auxiliary engine assembly is simple in structure, by means of the C-shaped ring installed on the clamping groove on the inner wall of the auxiliary engine shell body, the tight press of the main shaft pin and the upper cover is achieved, and at the same time, the adjusting function of the spring is improved. The car auxiliary engine assembly solves the problems that traditional auxiliary engine end covers are connected through bolts, loose phenomenon caused by metal fatigue is quite easy to occur, the main shaft pin is loose and invalid, and the car steering performance or driving safety is directly influenced. Therefore, the car steering performance and driving safety are greatly improved.
Description
Technical field
The utility model relates to the secondary machine assembly of a kind of automobile, belongs to technical field of automobile parts.
Background technology
A kind of C type of utility model ring compresses the secondary machine assembly of automobile of mode, also claims secondary group peptide, (English IDLER ARM).It is an accessory drive gear on the automotive steering structure; It is a vitals of automobile steering system; Secondary machine assembly is made up of annexes such as secondary machine body, swirl pin, bearing, inner ring, spring, loam cake, interior C type ring, seal ring and end caps, and secondary machine body and swirl pin adopt the friction of rolling component movement secondary.Automobile in the process that turns to, the transmission of tension member strength, secondary machine accessory drives is in the motion of high strength, high-frequency, swirl pin is also bigger to the impulsive force from pull bar, so the thrust and the fatigue resistance of secondary machine body gland are had relatively high expectations.
The mode of traditional secondary machine blade body and swirl pin assembling generally adopts the mode of end cap bolt together, promptly with bolt end cap is fixed on and carries out mouth end on the secondary machine blade body and seal.Owing to the employing bolt connecting mode, under the working environment of high strength and high-frequency vibrations, be prone to produce metal fatigue and becoming flexible of producing, cause swirl pin to become flexible and lost efficacy, and directly influenced motor turning performance or potential safety hazard.
Summary of the invention
The purpose of the utility model is: provide a kind of architecture simple; Good reliability adopts bolted connection to solve traditional secondary machine end cap, very easily produce metal fatigue and occur loosening; Cause the loosening inefficacy of swirl pin, directly influence the secondary machine assembly of automobile of motor turning performance or driving safety.
The technical scheme of the utility model is:
The secondary machine assembly of a kind of automobile, it is made up of end cap, seal ring, C type ring, loam cake, spring, secondary engine housing and swirl pin, it is characterized in that: through bearing installation swirl pin is arranged in the secondary engine housing; The swirl pin bottom is provided with spring through packing ring; The secondary engine housing inwall of spring below is provided with draw-in groove, and draw-in groove is equipped with C type ring, is provided with loam cake between spring and the C type ring; On the lower port of said secondary engine housing end cap is housed, is provided with seal ring between end cap and the C type ring.
The beneficial effect of the utility model is:
The secondary machine assembly structure of this automobile is simple; Through the draw-in groove on the secondary engine housing inwall C type ring is installed and is realized the compressing of swirl pin and loam cake increased spring controlled effect simultaneously, avoided traditional secondary machine end cap employing bolted connection with this; Very easily produce metal fatigue and occur loosening; Cause the loosening inefficacy of swirl pin, directly influence the problem of motor turning performance or driving safety, improved the turning efficiency of automobile and the safety of going greatly.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Among the figure: 1, end cap, 2, seal ring, 3, C type ring, 4, draw-in groove, 5, loam cake, 6, spring, 7, packing ring, 8, secondary engine housing, 9, bearing, 10, swirl pin.
The specific embodiment
The secondary machine assembly of this automobile is made up of end cap 1, seal ring 2, C type ring 3, loam cake 5, spring 6, secondary engine housing 8 and swirl pin 10; Through bearing 9 swirl pin 10 is installed in the secondary engine housing 8; Swirl pin 10 bottoms are provided with spring 6 through packing ring 7; Secondary engine housing 8 inwalls of spring 6 belows are provided with draw-in groove 4, and C type ring 3 is installed in the draw-in groove 4, are provided with loam cake 5 between spring 6 and the C type ring 3.On the lower port of secondary engine housing 8 end cap 1 is housed, is provided with seal ring 2 between end cap 1 and the C type ring 3.
During assembling, at first swirl pin 10, bearing 9 are put into secondary engine housing 8 endoporus, then packing ring 7 is put in bearing 9 bottoms; Again spring 6 is put into the inner ring of packing ring 7, and the filling lubricating oil, be pressed in loam cake 5 on the spring 6; With compression machine loam cake 5 is inwardly pressed, make spring 6 be contracted to loam cake 5 and touch till the packing ring 7, slowly be pressed into C type ring 3 in the draw-in groove 4 of secondary engine housing 8 this moment; When being pressed onto draw-in groove 4 positions, C type ring 3 can be sprung in the draw-in groove 4 by self elasticity automatically, unclamps compression machine then; On C type ring 3, add 2 seal rings and reveal, press end cap 1 to accomplish assembling at last to prevent butter.
The secondary machine assembly of this automobile is installed C type ring through draw-in groove and is realized compressing swirl pin 10 and loam cake with this; Increased regulating action through spring 6 simultaneously; Therefore can be in the middle of work because of the inefficacy that the high-frequency motion produces that swirl pin becomes flexible or reason such as metal fatigue causes; Avoid traditional secondary machine end cap to adopt bolted connection, very easily produced metal fatigue and becoming flexible of occurring, caused the loosening inefficacy of swirl pin; Directly influence the problem of motor turning performance or driving safety, improved the turning efficiency of automobile and the safety of going greatly.
