Compared with the prior art, the utility model, adopt two leaf spring structures, first piece is the spring steel material, utilizes its load that can bear all directions of its isotropic characteristics, has higher reliability, the second piece adopts the combined material leaf spring, utilizes its anisotropic characteristics, only bears vertical force, and the stress is simple, and its quality is less, satisfies light -weighted target.
Description
Technical field
This utility model relates to a kind of plate spring assembly for truck suspension, belongs to technical field of automobile parts.
Background technology
In prior art, truck leaf spring mostly adopts steel plate rolling to form, and weight is relatively big, and fatigue life is low; Some employing monolithic composite material plate springs, it adopts metal material transition with support junction, but due to the difference of metal Yu nonmetallic materials character, very easily causes junction to damage, and it is unreliable to connect.
Summary of the invention
Technical problem to be solved in the utility model is the defect existed for prior art, it is provided that a kind of lightweight, truck suspension plate spring assembly that structure is reliable, easy for installation.
For solving this technical problem, this utility model provides a kind of plate spring assembly for truck suspension, including upper plate spring sheet and lower plate spring sheet, intermediate pads, clip, rubber blanket and grasswort, described upper plate spring sheet is arranged on above lower plate spring sheet, intermediate pads is arranged on the root area between plate spring sheet and lower plate spring sheet, and three is fixedly clamped together by centre bolt; Described rubber blanket is arranged between the end of plate spring sheet and lower plate spring sheet and by clip clamping, and described clip is arranged in lower plate spring sheet, can limit plate spring sheet and gap between lower plate spring sheet; Described upper plate spring sheet two ends are provided with grasswort.
Described upper plate spring sheet is made up of 51CrV4 spring steel, and for parabolic type leaf spring, middle part is iso-stress structure, has structure thicker in end.
Described lower plate spring sheet is that composite is made, and its matrix material is epoxy resin, and reinforcement sill is glass fibre.
Described plate spring assembly front end is rotatably connected with plate spring front bracket formation by grasswort, its front end is rotatably connected with hanger formation by grasswort, described hanger is connected by revolute with leaf spring after-poppet, described plate spring front bracket and leaf spring after-poppet are bolted on vehicle frame, are fixed by U-bolts and vehicle bridge in the middle part of plate spring assembly.
Beneficial effect: this utility model compared with prior art, adopts two panels spring structure, and first is spring steel material, and it can bear the load of all directions to utilize its isotropic feature, has higher reliability; Second adopts composite material plate spring, utilizes its anisotropic feature, be solely subjected to vertical force, and stress is simple, and its quality is less, meets light-weighted target.
