At present, use the automobile of Leaf Spring Suspension, mostly use spring piot to carry out hinged transmission force and moment between leaf spring and band spring fixed end support, leaf spring and leaf spring shackle or hanger and the leaf spring shackle end support.Referring to Fig. 1, existing spring piot is generally cylindrical structure, such as the used spring piot of DongFeng Automobile Co., Ltd state 36 * 2 double steering tractor D310 vehicles, go out oil groove 2 what bearing pin body 1 was offered ring-type, open a minor diameter oil duct 3 at bearing pin body 1 cylindrical structure along central axis, the entrance point of this oil duct 3 is positioned on the end face of bearing pin body 1, the outlet end of oil duct 3 is connected with radially oil hole 5 on the oil groove 2, the entrance point of oil duct 3 is provided with grease nipple mounting hole 6, is provided with a semicircle positioning pin hole 4 at bearing pin body 1 and locates.But, during use under bearing load power or moment this structure low stress zones material more more than needed, material structurally distributes very unreasonable, and larger loss of weight space is arranged.
Summary of the invention
The purpose of this utility model is the deficiency that lays particular stress on for existing leaf spring pin structure to provide a kind of automobile steel plate spring pin, and the material of removing low stress zones reduces the weight of spring piot, and material distribution is structurally more rationalized.
For achieving the above object, technical solution of the present utility model is: a kind of automobile steel plate spring pin, be included in the oil groove that of the ring-type offered on the bearing pin body, in bearing pin body cylindrical structure, offer oil duct, the entrance point of described oil duct is positioned on the end face of bearing pin body, the outlet end of oil duct is connected with radially oil hole on the oil groove, the entrance point of oil duct is provided with the grease nipple mounting hole, on the bearing pin body, be provided with positioning pin hole near grease nipple mounting hole place, axially have lightening hole on the described bearing pin body, described lightening hole and oil duct parallel.
Described lightening hole connects the bearing pin body.
Described oil duct longitudinal axis departs from the axis of bearing pin body, and near oil hole one side radially, and the longitudinal axis of described lightening hole is near the axis of bearing pin body, and in the footpath of bearing pin body upwards away from oil hole one side radially.
Described lightening hole is irregular crescent shape.
Described lightening hole is circular port.
Described lightening hole is slotted eye.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is simple in structure, uses reliably, and mounting or dismounting are convenient, realized the lightweight of part.The design of lightening hole has alleviated the weight of spring piot, has reduced the cost of Leaf Spring Suspension.Length is 172mm, diameter be the spring piot of 40mm be designed to connect the irregular crescent shape of bearing pin body by the utility model optimal way lightening hole can loss of weight 0.5kg, weight-loss ratio reaches 31%.
Description of drawings
Fig. 1 is the spring piot structural representation of prior art.
Fig. 2 is the utility model structural representation.
Fig. 3 be among Fig. 2 B-B to sectional view.
Fig. 4 is the utility model assembling schematic diagram.
Among the figure: bearing pin body 1, go out oil groove 2, oil duct 3, positioning pin hole 4, radially oil hole 5, grease nipple mounting hole 6, lightening hole 7, dismounting clamping part 8, locating stud 9 is installed swivel nut 10, grease nipple 11.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail.
Referring to Fig. 2, Fig. 3, a kind of automobile steel plate spring pin, what be included in the ring-type offered on the bearing pin body 1 goes out oil groove 2, in bearing pin body 1 cylindrical structure, offer oil duct 3, the entrance point of described oil duct 3 is positioned on the end face of bearing pin body 1, the outlet end of oil duct 3 is connected with radially oil hole 5 on the oil groove 2, the entrance point of oil duct 3 is provided with grease nipple mounting hole 6, on bearing pin body 1, be provided with positioning pin hole 4 near grease nipple mounting hole 6 places, axially have lightening hole 7 on the described bearing pin body 1, described lightening hole 7 and oil duct 3 parallel.The design of lightening hole 7 has alleviated the weight of spring piot, parallels between oil duct 3 and the lightening hole 7 not to be through with a separation layer and to be used for the surface of contact that grease flows between spring piots and the leaf spring bushing by oil hole 5 radially.The grease that enters oil duct 3 is lubricated the frictional force when reducing the leaf spring motion by the surface of contact that oil hole 5 radially flows between spring piot and the leaf spring bushing.Positioning pin hole 4 is used for the location, prevents from that spring piot from skidding off when loosening to cause security incident.
Described lightening hole 7 connects bearing pin body 1.Described oil duct 3 longitudinal axis depart from the axis of bearing pin body 1, and close radially oil hole 5 one sides; The longitudinal axis of described lightening hole 7 is near the axis of bearing pin body 1, and in the footpath of bearing pin body 1 upwards away from oil hole 5 one sides radially.Described lightening hole 7 is irregular crescent shape, and length is 172mm, diameter be the spring piot of 40mm be designed to connect the irregular crescent shape of bearing pin body by the utility model optimal way lightening hole can loss of weight 0.5kg, weight-loss ratio reaches 31%.Described lightening hole 7 can also or be similar to the hole of above-mentioned shape for circular port, slotted eye, has realized the lightweight of part.
Referring to Fig. 4, spring piot of the present utility model is installed when hinged, inserts locating studs 9 at outer end positioning pin hole 4 and positions, and prevents play in the spring piot movement process, and locating stud 9 can pass through bullet pad, nut check.Grease nipple mounting hole 6 is threaded with swivel nut 10 is installed, and swivel nut 10 outer installation grease nipples 11 is being installed for adding grease injection.Grease is compressed into oil duct 3 by grease nipple 11, and the surface of contact that flows between spring piot and the leaf spring bushing by oil hole 5 radially is lubricated, and reduces the wearing and tearing that surface friction drag causes, extending steel plate spring suspension working life.Tool for assembling clamps during the 8 convenient steel plate spring pin dismounting of dismounting clamping part, makes the spring piot installing/dismounting convenient.The utility model spring piot is simple in structure, uses reliably, and mounting or dismounting are convenient, and are lightweight, reduced the cost of spring piot, easy to utilize.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, said structure all should be considered as belonging to protection domain of the present utility model.
